Looks like a WaA920 code but it doesn't jive with the joa stamp. The eagles wings look different from others I've seen, but I'm more used to seeing them on K98k's. Any ideas?
I'm no expert, but the bird looks fake to me. Looks like the stamps you can buy. That and the patina of the stamped indentations doesn't look to match the stock, looks to clean inside the stamp if you look at some of the other small dings that have retained their oils and aged dirt.
Just my amateur 2 cents...
